As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I've been developing apps and frameworks for several years (since I was in college). Pre-Vuo projects include Kineme Quartz Composer plugins, iOS apps for education, an app that analyzes photographs of tomato slices, and software to help people with disabilities use talking keyboards.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Your comment touches on some suggestions that other people have had for usability improvements: Background Color and More type conversions. We've had some discussions, but I don't think any community feature requests yet, about how in Max you can double-click on the graph and start typing to create a node, and how that idea might translate to Vuo. It would be cool if you could right-click on a port and get a mini node library of all nodes that could connect to the port, for example.
I wonder if some of the non-intuitive things will start to feel more intuitive as you use Vuo more and get used to its conventions. Like with Max, if someone's brand new to it, maybe they don't know that "matrix" means bridges for data, but they learn it from experience and then it makes perfect sense. With Vuo, maybe you don't know immediately that if you search the node library for two data types, like "object" and "image", you find nodes converting between them. So if things seem non-intuitive at first but then start to make sense over time, I wonder if there are things we can do to speed up the process.
Apple Motion's Replicator does a heck of a lot of different things. In Vuo the different things are split into different nodes, such as Copy 3D Object * and Tile 3D Object and Make Random Points Object and Arrange 3D Objects in Grid and Shuffle List and Change 3D Object Blending and Curve and Schedule and Make Random List (with Seed) and Make Gradient Noise and Make Points along Spline and Build/Process List.
